Principle A flexible sensing element actuates a microswitch by means of a lever. The set point is adjusted by means of a compressible spring installed in opposition. Set point and reset point must be between 10% and 90% of the selected scale. Standard factory adjustment Setpoint at 50% of the scale on falling pressure ustomer specific factory adjustment (option SETP) The following specifications have to be given with the order: Setpoint value Adjustment on falling or raising pressure Dead band value (as needed) when using an adjustable dead band switch Electrical connections 1 SPDT 2 SPDT OM OM Yellow / green OM Yellow / green Page 2 / 5

This table contains the deadband values for set point adjustment at 10% and 90% of the selected scale. For adjustable deadband the lower value corresponds to the deadband spring totally released and the higher corresponds to the deadband spring fully tensed. For other set points the deadband value can be calculated by linear interpolation between the values at 10% and 90%. For RPPN6 only. 3) For RPPN8 only. Page 3 / 5
